I feel like giving up

First picture is from today the second picture is from Nov 7th. I had this tank so nice and clear for like two months then I got a small bacterial bloom and bam now it looks like this… everything is the same, I just moved my Monte Carlo around, maybe I got bacteria in there on accident? It was set up with this same light for 2 months with no bacterial blooms and no algae or anything, Im doing water changes but I’m about to give up, I’ve just been trying to grow my Monte Carlo since like September. At this rate I don’t think I’ll ever get it ready to have shrimp.
